On 14 November 2019, Pre-Trial Chamber III of the International Criminal Court authorised the Prosecutor to proceed with an investigation for the alleged crimes within the ICC’s jurisdiction in the Situation Bangladesh/Myanmar.
Myanmar is not a State Party but Bangladesh ratified the ICC Rome statute in 2010. The Chamber considered that there exists a reasonable basis to believe widespread and/or systematic acts of violence may have been committed that could qualify as the crimes against humanity of deportation across the Myanmar-Bangladesh border and persecution on grounds of ethnicity and/or religion against the Rohingya population.
